Abstract (en)
[origin: US2013294603A1] A split architecture eMBMS with distributed BMSCs providing the same eMBMS service allows for a centralized key service where each BMSC is able to derive a set of MTKs from the MSK using the MTK-IDs as the differentiating input. This avoids the need to send MTKs to the BMSCs.
